Astronomers Find Dark Energy May Vary Over Time
A new study using data from NASA's Chandra X-ray Observatory and European Space Agency's XMM-Newton suggests that dark energy may have varied over cosmic time, as reported in our latest news release. First discovered about 20 years ago by measuring the distances to exploded stars called supernovas, dark energy is a proposed type of force, or energy, that permeates all space and causes the expansion of the universe to accelerate. Using this method, scientists tracked the effects of dark energy out to about 9 billion years ago.
